[PATCH] Fix AIX test failure due to replacement operator delete

[Jonathan Wakely]

On AIX the sized delete defined in the library will call the non-sized
delete defined in the library, not the replacement version defined in
the test file. By also replacing sized delete we make the test pass
everywhere.

        * testsuite/20_util/allocator/1.cc: Add sized delete, which fixes a
        failure on AIX.

This was broken by the recent change to make std::allocator use sized
delete.

Tested x86_64-linux and powerpc-aix, committed to trunk.
